PROBLEM TO BE SOLVED: To efficiently install a natural lighting structure on the facing surface without hindering flowing of rainwater and dropping of snow by arranging plural holding members along the flowing direction, arranging a natural lighting body between the holding members adjacent in the lateral direction, and arranging flowing water spaces along the flowing direction on the left/right side edge reverse faces of the natural lighting body. SOLUTION: Plural holding members 4 are arranged along the flowing direction so that a natural lighting body 1 is arranged between the holding members 4 and 4 adjacent in the lateral direction. Flowing water spaces A along the flowing direction are constituted of internal spaces of gutter members 5 arranged on the left/right side edge reverse faces of the natural lighting body 1. In the natural lighting body 1, the face plate part 12 is a harmonica shape composed of plural cells, and the molding part 11 formed on the side edge is constituted in the same as the molding parts 61 of longitudinally roofing adjacent facing materials 6 by sandwiching the holding members 4. That is, the natural lighting body is constituted of the folding-down part 111 folded down in a downward step shape from the side edge of the face plate part 12, the rising part 112 rising in an inclined shape from the lower end and the engaging part 113 to elastically engage with the engaging object part 43 of the holding members 4. |
